Technical note

How SDAT and IGS differ in practice

Geospatial coordinates are absolute positions on the earth, and they are large: a projected easting runs to six or seven digits, while latitude and longitude are small decimals. IGS expects a drawing laid out near its own origin in millimetres or inches. The geometry itself converts correctly, but it can land tens of kilometres from 0,0, or arrive at a scale where an entire county is forty units across. Zoom to extents first, then measure one known distance before dimensioning anything. Lettering in the image is traced as shapes, not recognised as text. Every character arrives as an outline that can be scaled and edited like any other geometry, but not retyped, restyled or searched, and no font is attached to it. Titles and callouts on a scanned drawing usually have to be typed again in the IGS if they need to stay editable.

Map Data Workflow

From map data to a working drawing

Converting SDAT to IGS usually means handing GIS data to someone who works in CAD. reaConverter makes that hand-off without a GIS seat on either side, for one layer or a whole delivery.

  • Convert every layer in a folder to IGS with the same settings
  • Go the other way too, from DWG to Shapefile, when the GIS team needs the drawings back
  • Render the same data to PDF for a quick review copy
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.

FAQ

SDAT to IGS Conversion

What are SDAT files?

SDAT is the data file of the SAGA GIS grid format. SAGA (System for Automated Geoscientific Analyses) is a free, open-source GIS widely used for terrain analysis, hydrology, soil science, climate studies, and other geoscientific work. A grid in this format is a map made of equal square cells, such as an elevation model, with one value in each cell. The .sdat file holds only these values in binary form, while a small text file with the same name and the .sgrd extension describes them: the size of the grid, its position, the cell size, the type of numbers, and the value that marks missing data. A history file with the .hgrd extension and a projection file with the .prj extension may accompany them. SAGA can also pack all of these files into one archive.

What are IGS files?

The IGS (Initial Graphics Exchange Specification) file format is a standardized CAD data exchange format used to transfer 2D and 3D model data between different CAD systems. Developed in the 1980s, IGES ensures compatibility across various engineering and design software by storing geometric data, annotations, and structure in a neutral ASCII or binary format.
